Centimeter Addition Measurement Worksheet

Kids can stall when measurement turns into tiny marks and labels, especially when the numbers need to be added. This printable page gives them four centimeter addition problems with illustrated measurement models, so they can read the saved quantities, add the centimeter amounts, and write each answer in cm.

This works best when a first grader already counts forward and recognizes cm as centimeters. The pictures help connect the written numbers to a measuring context, but they are models, not life-size measuring tools. Sit nearby for the first problem and ask which two amounts are being added before any counting begins.

The practice is simple: read the measurement, add the numbers, and keep the unit with the answer. If your child mixes addition and subtraction, try centimeter subtraction measurement practice afterward to compare the operation words in a familiar unit.

For a next step, have them say each full answer out loud, such as “six centimeters,” so the unit does not disappear. When centimeter addition feels steady, pint addition measurement practice helps carry the same add-and-label routine into a different measurement unit.
